Climate change is the biggest threat to all of civilisation our species has faced since the 80s. Scientists say rising seas will envelope major cities around the world while heatwaves will bring wildfires and torrential rains bring floods. And the global economy is stuffed.

But as if that wasn’t bad enough, it turns out that climate change might even mess up that most holy of traditions – your weekend.

The night out

The world’s most pre-eminent climate scientists have submitted thousands of reports warning of the danger of continuing to spew carbon into the atmosphere. And yet the governments of the world have continued to ignore them.

Thankfully, 42 breweries have weighed in to illuminate us about the true scale of the threat – we might actually run out of beer. From California to the Czech Republic, hop production is being hit by rising temperatures and a lack of water. Beer could also start to taste worse, according to the Czechs, but their beer is rubbish anyway.

“Changes in climate caused by human activity have the potential to create unprecedented social, economic and environmental challenges,” said a spokesman from Diageo, the company that owns Guinness. Maybe now people will start to listen.

But warmer air also holds more water, says Bob Ward, policy and communications director at London’s Grantham Research Institute on Climate Change. Meaning climate change will also bring more rainfall, “increasing the risk of flooding, both inland from rainfall and along our coasts due to sea level rise”. This all roughly translates to more of everything, except normal.

The dinner date

Carbon dioxide doesn’t just heat up the atmosphere, it also turns the ocean into an acidic soup that eats away the shells of much-loved molluscs. The ocean has increased in acidity by 25% since the industrial revolution. If it continues, many shellfish are in danger of disappearing from the fishmonger.

“This is an extremely difficult subject and nobody has the information,” he said. But if the situation in the US is anything to go by, there’s trouble ahead. In the Pacific northwest, the oyster industry has already lost $110m because of more corrosive water.

The dessert

The world is running out of chocolate. That’s because climate change and crippling poverty are driving Africa’s cocoa farmers to produce other crops. Which is a bit rubbish because your date’s chocolate mousse is set to get a lot pricier.

In four decades, the amount of land available for growing cocoa has dropped 40%. In the next 40 years, the temperature in Ghana and Cote d’Ivoire, where 70% of cocoa is grown, is set to rise by 2C. That’s going to make it too hot and dry for cocoa trees.

We’re already on the way to peak chocolate. By 2020, world cocoa demand is set to outstrip supply by 1m tonnes. That’s 90,909,090,909 Lindt balls.

The morning after

When there are people suffering in poor countries, there’s nothing worse than a hangover. Except maybe a hangover with no coffee. Annoyingly, the coffee growers of flooded Honduras and drought stricken Brazil and all those other places you didn’t know your coffee came from might not be able to get coffee beans to grow in a warmer climate …

Amazingly coffee growers don’t tend to drink much coffee. Maybe because they earn roughly half the price of a cappuccino a day..

The hair of the dog

You might want to hold on to that middling Châteauneuf-du-Pape you tore the budget supermarket price tag off so your friends thought you bought it at an indy bottle shop – it’s going to become a lot rarer.

The traditional wine regions of France, Chile, Australia and California are all going to become too hot to supply your favourite plonk.

Thankfully, you probably won’t have to go without. Just realign your snobby wine vernacular. As warm temperatures shift north, so will wine growing regions. So look forward to laying down a nice bottle of Swedish red for your grandchild’s birth wine.
